Patented Apr. 5, 1932 WILLTAM seems enssazze oi Montana REAR GUN steer Refiled for abandoned application Serial No. 184,666, filed April 18; I627. This application filed November The present application is a continuation in part of my previous application for patent Serial No. 184,666, filed April 18, 1927, now abandoned. is This invention relates to improvement in gun sights, to be used as a rear sight and in Combination with a front sight of any suit able make.

The present invention resides in providing it; a rear sight which is so constructed as to be simple, reliable and efficient at all times under most unfavorable conditions of weather and light.

A very important object of this invention 15 is to provide a rear gun sight whose sighting face is of narrow construction and appearing to the eye in the form of a post, that when in use it will obstruct but very little of the target or object aimed at, and which is slight- .29 ly greater in thickness than the thickness of the front sight itself, allowing the user in sighting to see nearly all of the target or object aimed at. 7

Another very importantobject of this in- 25 vention is that due to the sighting face being of such narrow construction across the sighting edge, any variation of the front sight away from the center of this rear sight will cause it to appear at one side edge of the rear 3%) sight, according to which side the variation is on. This variation will be quickly detect ed by the sighting eye and properly adjusted, thereby making a quick and accurate sight, and combined with the feature of allowing '85 nearly full view of the object aimed at makes such narrow Construction, it does not require any deep notch for the guidance of the eye in'centering the front sight, thereby entirely eliminating the blurring of the sights, which occurs with sights having a deep notch of 45 V or U construction.

Although I prefer the fiat top post sight,

I wish to provide the post sight in the other two forms'to meet the requirements of some users having special front sights to which To further Serial 1%. 222,981.

perfect this post sight in eliminating any blurring or reflecting of light, and allow a sharp outline of the edges forming the sighting face, the side faces are beveled or slightly cut away from the vertical side edges of the sighting face to the opposite end in direction of the muzzle, and I also cutor slightly bevel the surface forming the sighting edge, from the sighting edge downwards towards the opposite end in the direction of the muzzle.- j

A still further object of the present invention is. to provide any of the three forms of post sight in various color combinations to aid the eye in quickly aligning the sights and meet requirements of unfavorable light and weather conditions by cutting a narrow groove up the center of the sighting face and filled flush with some suitable material that will retain its color and hardness; such as, ivory or baked enainel.

This color combination contemplates hav ing the groove in' the sighting face of white color and the remainder of the sight of black' or blued color; and, in another colorcombi nation, it is contemplated to have the groove of black color and the remainder of'thesight ing face in white; and,-'in other forms" of sight to have the sighting face all white, or all blued or black. The above color coiribina tions are also provided to meet with the (life ferent type and color of front sight used therewith.

A still further object of this invention is to provide a transverse groove'at each end on the lower portion of the post sight and adapted to be engaged by suitable members formed upon the base of sight,'. for quick and easy means for attaching and detaching the post sight when changing from one form of sight to another to meet the requirement of conditions.

At the same time; it will be noted that the side edges of the post sight are at right angles to the horizontal, aiding the eye Figure 1 is a side elevational view of a portion of a gun barrel with the front and rear sight applied thereto in the manner in which the same are sighted on the target,

Figure 6 is a group view showing a folding sight; in folded position, in extended position and in side elevation,

Figures 7 and 8 show rear and side elevations of a slightly different form of sight, having transverse grooves,

Figure 9 shows a side elevation and the mounting block for the sight construction shown in Figures 7 and 8.

Referring particularly to Figures 1 to 3 inclusive, the gun barrel is indicated at 1 which is provided with a front sight 2, of a well known type as now used in the art, while the rear end of the barrel is provided with a clove-tailed slot extending transverse- 1y of the barrel, as indicated at 3, for receiving the dovetailed base member 4, carrying the improved sight forming the subject matter of this invention indicated at 5.

This sight 5 is of relatively narrow thickness in rear elevation as shown in Figure 3 and of substantial length or width as illustrated in Figure 1, having the proper height for cooperation with the front sight 2. The opposite sides of the rear sight 5 are parallel, the upper end of the post squared, as indicated at 6 in Figure 3, the rear face thereof being provided with a suitable strip 8 of black material, and positioned in the central portion thereof with the opposite edges parallel to each other and the side edges of the post sight.

In sighting a gun equipped with these sights the sighting eye will be located as shown in Figure 1 at 9 and the line of sight to the bulls-eye of the target is indicated by the dot and dash line 10, so that the front sight will be viewed over the rear sight as indicated in Figure 3.

The blackened strip 8 will assist in obtain- 1 ing the proper centering of the front sight over the rear sight, as shown, in order to obtain an accurate aim of the gun on the bullse e.

The sight, having the strip 8 in the cen tral portion, is of most serviceable form as the white and block color strips readily adapts the sight for cooperation in obtaining proper alining of the sights on any objectwhether it be light or dark, as one or the other posts of the rear sight will form a contrast with the object aimed at and the condition of the light at the time.

For certain purposes, to meet special requirements the sights shown at 11, 12 and 13 are provided, in which the sight 11 has the rear face shown in white color and sight 13 provided with a totally black or blued face, while the sight 12 has a black strip extending vertically up its center against a white background.

. The sights 11, 12 and 13 may have the upper edge forming the sighting edge which cooperate in aligning the sights, concaved as shown at 15 on the sight 12 or a very shallow notch 14E of 120 angle as shown on the sight 11, or a plain square edge 16 as shown on the sight 13, although the plain flat edge has been preferable for most uses. The concaved sight 12 is particularly well adapted for target shooting, the concaved upper edge extending longitudinally of the device and coinciding with the curvature of the bulls eye of the target to indicate the proper sightingof the bulls eye by placing the sight so that the bulls eye will appear therein.

In Figure 6 there is illustrated at 17 a side elevation of a sight construction made as shown in Figures 1 to 3, in which the rear sightindica-ted at 18 has the special pivot mounted on the clove-tailed base 19 through the medium of a pin 20 and extending through the central portion of the lower end of the sight 18 and terminating in ears 21 mounted in spaced parallel relation on the base 19.

This permits of the sight being raised to the vertical position as shown in dotted lines in the View as indicated at 17 and in the full lines in the central view indicated at 22, while a side elevation of this structure is indicated at 23. The sight 18 in position as shown at 17 permits use of a rear peep sight by those gunners desiring use of peep sight for target shooting. In Figures 7, 8 and 9 a removable post sight construction is illustrated in which the sight is indicated at 24:, which is of rectangular form as illustrated in Figure 8 in side elevation, and provided at the front and rear ends with notches 25. The front notch in the sight 24is adapted to engage the lip 26 in the slotted portion 27 of the base plate 28 so as to lock the sight in vertical position on the base plate, which is suitably attached to the gun barrel. The rear notch receives the spring pressed pivoted pawl 29 having the projection 30 thereon seating in the notch and a projection on the opposite end engaged by the spring 31, which is of a short length leaf spring having the free end thereof seated at the rear end of the notch 27 in the base 28 as indicated at 32, this leaf spring normally tending to rotate pawl 29 so as to move the end 30 toward the bottom portion of the slot.

In order to remove the sights from this base portion 28, it is necessary to rotate pawl 29 on its pivot by lifting the rear end of the sight upwardly. There is sufiicient motion between the parts of the plate and the sight 24 as to permit of this motion to assemble or disassemble the sight in the slot in the plate.

It will thus be seen that a substantially simple form of removable sight construction has been provided as above described.

When aiming any one of the sights above described on a target, the front and rear sights are alined as shown in Figures 1 and 3, along the center line 10, which extends to the bulls eye 33 of the target 34: and in which the front sight indicated at 35 has the upper end viewed over the square upper end of the rear sight 36 so as to represent a square and with the sighted post structure having the black cen ter, as illustrated in Figure 3, it will be seen that this squared portion of the front sight and rear sight is alined with this central sight in the post.

It will be further noted by reference to Figure 5 that the post sight 36 being relatively narrow and having parallel sides obscures a substantially small portion of the target in view with the result that it permits of a substantially full View of the target and promotes the efficient centering of the front sight with the rear sight, in order to permit a quick aim as well as a very accurate aim at the bulls eye 33.

It will thus be appreciated from the above description that a highly novel form of rear sight for guns has been provided by this invention, which substantially improves the construction of the sight for guns over those previously used, in that the post rear sight allows substantially full view of target and object aimed at and the tendency of the rear sight to become blurred in alining the sights of the gun on the target is entirely elimi nated; my invention being characterized in the shape and construction of the sighting face of the rear sight, being of narrow width, three thirty-seconds of an inch to three sixteenths of an inch, according to the height, for small arms, differentiating from those rear sights of prior art having a sighting face of broad width transverse of the gun barrel.

Having thus described my invention, what I claim as new is:

1. A rear sight for guns comprising a fixed rectangular plate with its longer side extend ing longitudinally along the barrel, the width of said plate being substantially greater than its thickness, and means for attaching said plate in uprightsighting position to a gun barrel.

2. A rear sight for guns comprising a fixed rectangular plate with its longer side extending longitudinally of a gun barrel, said plate providing a rear sighting edge of relatively narrow thickness having vertical side edges parallel throughout the height of the sight and means for attaching said plate to the gun barrel in upright sighting position.

8. A rear sight for guns comprising a relatively thin plate, means for attaching the plate to a gun barrel in upright sighting position with the attached edge extending 1ongitudinally of the barrel whereby to provide an elongated upstanding rear sighting face there being a shallow sighting groove extending longitudinally in the upper edge of the plate.

a. A rear sight for guns comprising a rectangular plate with its lower side extending longitudinally along the barrel, the width of said plate being substantially greater than its thickness, means for attaching said plate in upright sighting position to a gun barrel, said plate having a vertical groove formed in its sighting edge and a filler for the groove of a color contrasting from the sighting edge of the plate, the width of the filler and the portion of the plate at each side of the filler being of a substantially uniform width and the side edges of the filler and the plate being parallel throughout.

5. A rear gun sight comprising an upright member of rectangular shape positioned on the gun barrel with the plane of the faces of the member extending longitudinally and with the rear edge of the member constituting the sighting edge of relatively narrow thickness whereby any deviation in alinement of the sight with respect to the eye and the object at which the gun is aimed will reveal a portion of one of the faces of the sight and means for attaching the lower edge of the sight to the barrel.

In testimony whereof I affix my signature.
